The website does not provide an option I need to complete box 18-20. Do need to switch to another software.

Please explain the problem.   Boxes 18-20 are for local tax on your W-2.  Often those boxes are blank if you did not have a local or city tax.

W2 boxes 18-20 are on the screen.   You probably have to scroll way down.  They show up on my computer Premier version.
