I e-filed my 2019 taxes on March 26, 2020. Then I realized I omitted to include one of my EFTPS prepayments. The return was accepted by the IRS. On 6/22/2020 I entered the additional tax payment and the Federal Refund calculator jumped by that amount. After completing my changes I printed and the 1040-X Amended file shows I have a refund due, which is the same amount I entered. On lines 21 & 22 the additional payment amount is shown as if it is a refund, but it isn't. The form 1040-SR correctly applies the additional prepaid tax with the correct tax due on Line 23, but it doesn't show it is amended. Not sure if I just send all of these forms to the IRS. Need clarification. Thanks.
