No, you cannot put stuff you forgot to enter last year on your 2025 tax return. You can, however, amend your 2024 tax return to enter them.
Wait until your original return has been fully processed before you amend, and make sure you have saved a pdf of the original return before you amend. (If you do not save it as a pdf, the amended return will overwrite the original, and the original will be lost forever)

Use a mailing service like certified mail to track so you will know it was received since you will have a long wait.
Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.

You will need the 1099R----get it from the custodian of the 401k.
