since she has already filed, if the return is accepted there is nothing you can do but file an amended return after the original return is fully processed - you receive your refund or your payment is cashed. you have your work cut out for you first you have to enter the Turbotax return using the same info and numbers on the original return she filed.

the good news is that you should be able to e-file the Federal amended return. if you have a state return that will also need amending and probably will have to be mailed in
