I needed to amend my tax return because I forgot to add 2 other W-2 forms. I did my 1040X using turbo tax, and I sent out my letter last week but it got delayed and now it’s on the way to Austin,

Receiving your amended tax returns back takes a long time. Usually, it takes about 3 weeks from the date you mailed the amended return for it to show up in the IRS system. Thereafter, you can get your amended tax refund after 12- 16 weeks.
