the question might sound dumb, but can anyone check to see if the sentence is correct:

It's(form) due till May 1st.

It's not a dumb question; many people mix up its and it's. You've used it correctly.

It's due May 1.

or

It's not due til May 1.

To check if the sentence is correct, we need to determine whether it follows the grammar rules and makes sense in context.

Looking at the sentence you provided: "It's(form) due till May 1st."

It seems like you might be missing a word or inputting the wrong form. If you meant to say "It is due till May 1st," then the sentence is grammatically correct. However, if you meant to use a different form, please provide the correct word or form so that I can help you further.
