You are right, thank you. The vouchers are indeed Form 1040-ES and are automatically added to the PDF if some conditions are met, as explained in the FAQs.
1) We did not know the existence of Form 1040-ES, and obviously we did not know it is not mandatory to pay the estimated taxes (though encouraged in order not to have future problems with IRS)
2) We recall reviewing the filing options and either selecting or thinking about how to pay in installments. We do recall now that once the PDF was printed out, we were surprised to find out there were the 4 vouchers for the correct amount we owed the IRS. Hence we assumed those were indeed the checks we were looking for and in total confusion we thought we actually selected the correct option.
3) We do not recall having seen any instruction, warning, or alert about those estimated taxes for 2020. Because of our current economic hardship, we certainly would not have paid right now. We are even lucky there were enough money for the IRS to take in the first place... This is something for TurboTax to think about!
4) It's interesting that IRS admitted the mistake by phone, but I can imagine how he did not understand my case. I'll call again next Monday.
Now, is there any luck to get at least the 2k we payed for 1040-ES back?
Thank you again.
