It took like 11 weeks to move from "Received" to "Adjusted". Wonder if I have to still wait for the complete process to finish before I can submit mine as it is depending on that correction to go through (he marked himself as "Nobody can claim me as a dependent" accidentally.
Waiting for your son's amended return to be fully processed is not going to help you e-file your own return. It will still take a VERY long time for the system to show that he changed his return. You can only file your own return that claims him as a dependent by mailing your return. You cannot e-file this year at all. Print, sign and date your return in ink, and mail it.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
since he filed his return and did not indicate he could be claimed as a dependent, even after his amended return is fully processed, you may not be able to e-file yours. Doesn't hurt to try but if you get a rejection code ind-517-01 you'll have to mail yours.
