I have something similar. UFile Premium messed up the filing...got it's wires crossed.
The situation: I have me and my spouse's tax return to file. We can file electronically using NETFILE.
I had my spouse selected across the top menu, and then clicked "File my return now" button for myself, but my spouses submitted. I had to click on my name across the top, then click the "File my return now" button. Then it worked for me.
Good luck,
J
UFile Premium Product Management:
As a user, when I click the "File my return now" button next to my name, regardless of if my name or my spouse's name is selected across the top, I expect the button next to the name to take precedence of the filing intention, not the name across the top.
