There is no requirement about "data" in the GDPR, so provided this is just "data", no. An empty form with fields for personal data contains no personal data.
On the other hand, if the form is filled in by the user with personal data (as defined in GDPR article 4), and you receive a copy of the filled in form and process these personal data (as defined in GDPR article 4) - then the answer is: Yes.
However, if you do not process the personal data (i.e. the form is just printed out on paper and filled in with a pen, and nobody except the data subject has access to the piece of paper with the filled in form - then the answer again is "no").
