How long does it take to get your amended return back

[Lisa995]

It can take anywhere from 12-20 weeks after you mail the amended return in for it to complete processing.

I did not know you had to mail it in mine was accepted on the E return thing so is it yes I have to mail it back in

[Lisa995]

"mine was accepted on the E return thing"

What you saw was the acceptance of the original return, not the amended one.
 
Yes, amended returns MUST be printed, signed and mailed in.
