The 1040 is only 2 pages.
I don't know what you mean by "break in the line under the amt where the comma is"
If youre seeing weird printing behavior, restart both your computer and printer and see if that brings it back to normal.
Meaning the line under the $ column on the right side of the 1040, where the comma is , shows a downward slant and then continues to the right slightly lower to where it ends on the right side of the page. So the line under where ach $ amount is shown is not straight. I can't replicate it on a key board but can show you a pdf copy of the 1040 if there's a way to get thet to you
If you print to PDF, then print the PDF does it happen?
Double check your Print Options and be sure the correct printer is still chosen for tax forms, Ive seen people mention that a Windows update has changed their default printer.
