Already mailed my return status says ready to mail. How do I check my tax return status?

[Lakeisha]

If you mailed in a regular Return we ask that you allow up to 21 days for the Irs to process your Return.

You can go to Irs.gov to check the Status

If you have filed a Amended or "Corrected Return this can take longer

All amended tax returns must be filed by mail. If you have already mailed your amended return, it can take up to 3 weeks to show up in the IRS system.

You can check the status of your amended return by clicking the link below:
