Please only reply to this post if you know how to resolve this issue.

Issue: The client originally filed as Single for their 2022 1040. However, the client later informed me that they got married in 2022. I amended the return in July 2023 from Single to Married, and the client received their refund (the wife had no income in 2022). The client recently received a CP 2000 notice because they omitted their 2022 1099-B form. How do I amend the amended 1040X, and since the client already received the refund from the first amended return, how do I account for that in the second amendment?

Thank you~!
