You can try the No for the withholding but that may get rid of your form 2210 if you wanted to see what was in it
(And NO, you cannot combine your "estimated" tax payments with the withholding. the software is supposed to use the dates and amounts you actually entered for your estimated payments, and adds them in where needed).

Another thing to make sure of, is that you have accurately entered your actual 2019 tax liability and 2019 AGI. IF you transferred in your 2019 tax file to start this year's forms, the correct numbers were in there...but if you stared with a blank file where you hare entering everything entirely form scratch, then you need to look at your actual 2019 tax forms to see what's there.
