I received my corrected W2 the other day after I had already filed my taxes. What am I supposed to do nw?

That depends----maybe nothing----what did they change?  Did they change your income or federal/state tax withheld?   Or did they change something else?

Depends on what what changed ... which boxes have changes ?

What you have to do could also depend on the amount of the change. A very small change might not require doing anything, whereas a significant change of certain boxes might require filing an amended return. So provide more details. Which boxes on the W-2 were changed? Did they increase or decrease? How much was the change. If box 12 or box 14 was changed, include the code or abbreviation of the entry that was changed.
