I don't think you understand. My income varies significantly throughout the year, so I make federal and PA estimated payments based upon the income for the given period. TuboTax federal form 2210 works just fine. As I indicated earlier, TurboTax PA Rev1630 is a nightmare. It is difficult to access, it doesn't transfer payments properly (in 2018), and it calculates incorrectly (to the tune of $170 in 2019).
