I printed/downloaded my 2018 federal tax return, but it's not showing lines 37 through to 47 on there. I tried printing through the print center and it still doesn't work

Are you expecting there to be entries for those lines?

The tax forms were changed this year and the line numbers aren't sequential on a single form anymore.  You may not have certain lines on your tax forms.  Lines 38-47 now appear on Schedule 2 - Tax.  Most of these lines are actually not being used - the two entries that would appear on this form on for Alternative Minimum Tax and Excess advance tax credit repayment.
