Unless i'm doing something wrong, the fine adjustment on the printer setup does not 'stick'.  I have to set the vertical at -15 so the name address shows properly in the envelope window.  Sign out and back in again and the setting is back to zero and the checks print as before - name too high.

And I agree with everyone here - shame on Intuit for forcing us to use 'their' check forms and envelopes.   You're a software company, not an office supply company - stay in your lane.  Pretty much every other form has an editable template except, of course, the one that requires the highest % of paper output.
