Why Turbotax force me to fill form 2210 when I try to file today, 4/30, knowing that I am a Florida resident, therefore there was an extension to file until May 1?

That penalty is not for filing late, the IRS will not impose a late filing penalty if you file by 05/01.   Form 2210 is an underpayment penalty.

 

Try to delete the form (2210).    If you can't delete it, search for penalty, use the Jump to link and then go through the interview and answer the questions to remove it from your return.
