2020 tax year amendment letter and where federal payment should be mailed

[meo]

Two questions:

Amending 2020 1040 for federal and WI to be e-filed. Amendment letter does not include state information and if I insert code, it only references MAILING the return and doesn't include any mailing information. (efiling WI amended is allowed in ProSeries). Am I missing something here or is it an oversight in the software?

The instructions for the federal payment and 1040-V voucher shows mailing address for the payment (for the amended return) as Kansas City and the federal 1040-V instruction (above the cut here dotted line) shows payment should be sent to Louisville. Which is correct?

Can't the client just make payment through IRS Direct pay and choose Amended Return as the payment type?
