I'm still confused. If you log in to your online account, and at the Tax Home there is a "Take me to my return" button still showing, and the Return Status says "in progress", that means a return has not been finished and filed in that account. If you are sure you filed, then maybe you have another account.
Please say exactly what wording you are seeing when you enter your return info at the IRS website.

If that tool finds no evidence of your return, then that's more indication that you haven't filed.
How do you think you filed? By efile or by printing and mailing?
If you think you efiled, what shows up with this efile status check tool?
