First, read this helpful FAQ to see if you need to amend. If yes, continue below. https://ttlc.intuit.com/replies/3318732
Since you have
already filed you
will need to wait until the IRS either rejects or accepts your return. In the meanwhile, DO NOT go
in and make any changes to your return. If your
return is rejected,
you will be able to go into your account and make the necessary changes and
re-submit your return. If the IRS accepts your return, you MUST wait until it has been fully processed and you receive your refund or
have paid your balance due. You will need to prepare an amended tax return on a
1040X and mail it in. You cannot e-file an amended
return. They have to be mailed, and it takes up to 16 weeks for the IRS to process an
amended return. 3 weeks after you mailed your amendment, you can start tracking
its progress at the IRS Where's My Amended
Return? site.
