Who at the IRS told you they had not received your filing? If you are relying on the IRS refund tracking web site, you can't use that to track a tax return where there is no refund.
When you say transmitted, did you efile your return and was it accepted, or did you print and mail your return yourself?
You can verify an efiled return was submitted and accepted using this link: https://shop.turbotax.intuit.com/efile/efile_status_lookup.jsp
If you printed and mailed your return, the IRS did not process any mailed returns for several weeks so it's not likely they would know whether they received it or not unless they have opened it and started processing it.
