If I use the estimated payment vouchers, can I enter a different dollar amt than the amount Turbotax pre-populated in the amount field?

If I make one estimated pmt, must I make all 3?

It is optional, you can pay different amount, do just one payment, or not to do estimated payments at all. Depending on your situation, you might or might not be a subject of underpayment penalties when you file your next tax return. The estimate payments vouchers always provide you approximate amounts based on your current situation, which could change in the current year.

Don't try to modify the generated forms. You will contradict the bar codes. 

get the blank form in fillable PDF format  from the IRS site.
