No, they have same meaning.
The apostrophe ' simply replaces the o in the word 'not'. It is called a contraction.
The pronunciation is different. Instead of saying two clearly separate words, 'have not' only one word is said as 'havunt'.
Having "Not" as a separate word creates more emphasis eg, "I didn't go there" is not as strong as "I did not go there".

you shouldnt use contractions in the form you were filling out

this site is - - - different, in that people write as tho it is speech. slyiy ascribing to others contractions which show ignorance or prejudice
Although they both have the same meaning, the form without the apostrophe can be used to add stress to a statement, especially when spoken.

For example, "I haven't had a Covid vaccination" is simply a statement that one hasn't had the jab, whereas "I have NOT had a Covid vaccination" might be used by someone who wishes to stress that they've absolutely no intention of ever having one.

Back in my school days (over half a century ago) we were taught that the shortened forms ("haven't" and "didn't") should only be used in reported speech, with the full forms ("have not" and "did not") being used at all other times in written English. These days though, it's far more common for written English to follow spoken English, making the shorter forms fully acceptable (and, indeed, sometimes a little better, as the text then flows as freely as speech would).
On the other hand, there's a world of difference between 'sanction' and 'sanction'. :-)
the first ones in each pair are simply contractions of the second used in normal speech and writing. As chico says, we sometimes use the not to emphasise an attitude more strongly. eg No I did NOT nick your bike.
Did you mean to type that Arrods??
sanction is a a contronym.
Was it not an example of a word with opposite meanings?
Yes, it was just to emphasise some of the peculiarities with the English language.
'Cleave' is another word with opposite meanings.
"Have not" is also slightly more formal than "haven't", so you might want to write the first in formal business writing such as reports, or academic writing. But most of the time, writing the contractions "didn't" or "haven't" will be fine.
Let and dust are other examples and there are many more.
Sanction, cleave and buckle were the three answers to a question, about the meaning of words, on University Challenge on Monday - so perhaps still quite fresh in some minds....
Why do most folk say and write, "aren't I" rather than, "amn't I"?
"Trim" is very common one.
well you live and learn.
"Trim" is very common one.
be carefull ttt, as this word has several meanings.
"Haven't" is a short form (or contraction) of "have not."
"Didn't" is a short form (or contraction) of "did not."

The long form and short form mean the same.
The difference is only in the context. We usually use the short form in speech. If the long form is used in daily speech it is mainly to emphasize the negative meaning.
It is not acceptable to use the short form in academic and formal writing.
