How can I check to see if the IRS received my amended tax return?

[Critter · Accepted solution]

Three weeks after you've mailed your amended returns you can start tracking its status using the IRS "Where's My Amended Return?" tool or by calling their automated number 1-866-464-2050.

Do keep in mind; it can take 12-16 weeks for your amended returns to be processed.
