Schedule C Client's old CPA  did amended returns when outside service processed 941x returns

Client was caught in the delay and old CPA did second amended return because refunds didn't look like they were coming.

IRS had questions and didn't process second 1040x

In mean time IRS took from a 23 refund the amount due on 1st amendment

Now client actually receives 2020 ERC first part of 2025 .

Client wants us to refile the second amendment get a refund for the interest paid and then add the ERC money to the 2025 return as  taxpayers can now do

Feels wrong but got any good reason he can't other than just no.
