Were you divorced by the end of 2018? If you were not divorced then you could not file "Single" for 2018--your filing choices would be married filing separately or married filing jointly. If you were divorced by the end of 2018, then "Single" or possibly "Head of Household" would be the correct filing status for you. If you were Single or HOH for 2018, your ex has no right to see your tax return. If you should have filed as MFS, then there are rules for that filing status that you have to follow. When you file MFS then both people have to itemize, or both have to use standard deduction.
