I DID NOT COMPLETE MY 2019 RETURN WILL THAT SLOW MY STIMULUS

No.  The stimulus is an advance credit on your 2020 tax return.  The 2019 tax return is not relevant for the stimulus payment any more.

If you do not receive any other stimulus payments by January 15, 2021, then the stimulus payment for which you are eligible to receive will be entered on your 2020 federal tax return as a tax credit on Form 1040 Line 30.

The TurboTax program will ask about stimulus payments in the Federal Review section of the program.
