Original tax due
I e-filed in Feb and was accepted. The forms showed I owed $19862 for 2020 (Fed) and about $5k (State). Being so early, I did not pay either amounts. Later I discovered I failed to enter estimated 2020 taxes paid quarterly which reduced my 2020 tax bill to $0 (Fed) and a refund of $3k (state). I have since amended the 2020 taxes and am getting ready to mail them in. Now it says I owe no balance and will not receive a refund from the feds. Also, it did not provide estimated payments for 2021 My question is - Do I still have to mail in the original $19862 to the feds on the original form 1040-V OR can I produce my own 1040-ES forms and pay 2021 estimated quarterly that add up to approximately $20K.
