I don't want to file the 2020 return or pay the estimated tax for that year, only pay the Form 1040-ES Q1 amount through ProSeries for 2021. When I try to file electronically, it looks like ProSeries will e-file the 2020 return and that's not acceptable. So, either ProSeries will do what I want, or not, because I can't tell what happens if I e-file. Come on ProSeries: clarify what will happen if I execute the e-file command to only pay the Q1 Form 1040-ES amount.
