After you file

I finally got back and able to review my taxes. Turbo tax mysteriously added 3 more digits to income earned while a non-resident thus making my Maryland adjusted gross income  -$451k +
Now I have to deal with this mess. Doesn’t TT have accuracy guarantee?

So now what do I do?

I am sending my W2 and end of year paystub. Do I have to file an amendment?
