Each tax year and each refund is separate. You cannot combine tax years, nor does the IRS combine refunds from past years and include them on a current year refund. If your 2023 return was rejected then it was never filed, never processed, and you will never receive that refund unless you print, sign and mail the 2023 return to the IRS. It cannot be e-filed now; e-filing is closed for 2023 returns so the only way to file it is by mail.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
