@sjbhermosa It might affect her refund especially if she has the recovery rebate credit for $1400 on line 30 of her return. If she is a dependent on someone else's 2021 tax return she is not eligible for the $1400 and has to pay it back.
Even if she amends, your return claiming her cannot be e-filed this year. It will be many months before the IRS processes her amended return, so you will need to print, sign and mail your own return.
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.
