I've already done & received my taxes for 2025 but I forgot about a W2 from a job I only worked 2 months at?

I need to amend my taxes with a W2 I forgot?

As of 2/26/26, TurboTax's website is showing that the 1040X won't be available until 3/4/26. Don't hold your breath. Its availability has already been pushed back from late February.

Once your original return is accepted and the finances are settled, you can file an amended return. Since it was a short job that you forgot about, it may not have been much income. If the effect on your taxes is less than $25 in additional tax liability, you are not required to file it. You may want to for additional refund or change in credits.

• Save a copy of the original return before doing an amended return.
• If you aren't sure, you can use the Should I file an amended return? to help determine if you should file an amended tax return.
