Can I find out when my refund will be processed once e-file said it was rejected? Does my mailed in paper form get listed on the site of "where's my refund"?

Yes, once the IRS receives and accepts your paper return, it will update on the Where's My Refund website. It can take up to four weeks for it to be accepted.

"Where’s My Refund? will give you the status of your refund. You can check the status within 24 hours after we’ve received your e-file return or 4 weeks after you’ve mailed a paper return. It has the most up to date information about your refund."

Thank you for the time frame.  It's been 2 1/2 weeks so I was worried that it wasn't getting to the proper department to be processed.
