Also, how do you know the IRS did not receive your return? Did you actually speak to a live IRS agent, or did you use the "Where's My Refund" tool at the IRS website?
If you only used the IRS tool at https://www.irs.gov/Refunds , be sure you used it correctly.
NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund. The amount to use is on your Federal Form 1040, Line 20a.
