@shoequeen101 NO!!!! Just be patient... IRS is woefully backlogged.  Figure 6-9 month backlog for paper filed returns.  Just relax!

If you mailed in the return then prepare for a long long wait ... paper returns are taking 6 months or much much longer to process again this year.  And until the envelope is opened  and the data input operator enters it in the system the WMR?  tool will not even show it in the system for processing.   Check this tool once a week until you see it in processing :  https://www.irs.gov/refunds

DO NOT MAIL IN ANOTHER COPY.
