You will need to amend your tax return. However, you should not try
to amend your return until it has been fully processed and you have received
your refund or your payment has cleared. Amended returns do
not “catch up” to your original return and replace them; they are
processed as two separate returns.
Amended returns have
to be printed and filed by mail. It can take the IRS up to 12 weeks or
longer to process them. If you are due a larger refund than on your
original return, your amended return should only show the difference and you
will receive a separate check for it. If you owe money on your amended
return, it will show only the new amount owed, you will have to mail a check
with the return.
Please see the TurboTax FAQ below for instructions on how to amend your 2015 tax return.
Let me know if you
have further questions.
