First, make sure your filing status is married filing separately, as nonresident aliens cannot file a joint return. enter a dummy number for your spouse in the form of an ITIN, like 99-99-9999. That will let you print the return. White that out and write NRA instead. Do the same for your Ohio return which must be married filing separately as well. If you don't owe anything, it's not that crucial to file on time or file for an extension, but if you do owe taxes, you should file ASAP, if you can't file for an extension on time.
