Forgot to sign return they sent it back i signed it will my refund take longer and my refund never shows up on the irs website and why wont it show up

If the IRS sent your mailed return back, you will need to sign, date, and re-mail it.

It can take up to 4 weeks for a mailed return to show up in the IRS "Where's My Refund" tool.

You should be able to use the tool below after about 4 weeks from re-mailing it.

It can take  approximately 6 weeks to get a refund after filing by mail.
