Personally, I have two customers with amended tax returns sitting untouched by the IRS for many months. Tax Advocate Service has not been helpful to this date.
I would certainly understand not wanting to deal with the 2022 issue at all.
I would file the 2023 tax return with the information that you currently have.
After that refund has been received, then amend the 2022 tax return.
After that amendment has been approved, then amend the 2023 tax return.
I say this knowing the complete process will stretch out for months on end.
I have not found the audit risk to be enhanced but everyone seems to have their own opinion about that issue.
