This answer is to a slightly different question of accessing previously filed taxes.
The help forum wont let me post directly on this question (there's no Reply button)
I noticed in 2023 that they hid the "Tax Home" that previously appeared on the left column.
After logging in hit the "Continue" button - as though you were about to file for the current year (trying to force you into filing with them again).
After pressing "Continue" you should see "Your tax returns & documents" near the bottom
