I want to skip form 8880 IRA tax credit

That credit is automatic based on your entries in TurboTax, but if you want to delete that form you can try the following:

A simple way to delete forms in TurboTax online is to use the Tax Tools menu option, which is on your left menu bar when you are working in your program. Then, choose Tools and then Delete a form.

If you are working in the download TurboTax program, use the Forms Mode on your menu bar to bring up the form you want to delete, then choose the Delete Form option at the bottom of the form.

Form 8880 cannot be simply deleted.  If you delete it, it will be regenerated automatically.  The only way to force TurboTax to remove Form 8880 when you qualify for the credit is to tell TurboTax in this section that you were a full-time student, disqualifying you from receiving this credit.
