I need to amend my most recent federal return. it is about $1200 less than expected. the links to amend since its been accepted are not showing on my turbotax page as sai

If you are trying to amend your 2023 tax return, you must wait until it is accepted and processed.  Check the status and if it's still pending, do not make any changes. 

If your tax return is rejected, you may log in to TurboTax and make changes along with fixing the rejection. If your tax return is accepted, once it’s processed and you receive your refund, you can file an amendment through TurboTax using Form 1040-X.

For further information review the TurboTax articles: How to Correct Federal Tax Returns and Video: How to Amend Your Tax Return.

no rush. Tentatively the 1040-X won't even be available until the middle of February.
