Assuming you are using the Desktop software to attempt these entries (not the Online browser-based software)

1) Medical expenses have an issue, where you cannot make a direct entry if "$0" shows on an interview entry line...You can try to click in the box an then go up to the menu and click on <Edit<Add Supporting Details and a Supporting Details sheet  "might" show up where you can either enter your details, or hit the red "X" to delete the sheet entirely, and then enter a number on the main interview in the normal manner. .............. IF..IF that doesn't work on that same pages, switch to Forms Mode and a Medical expenses worksheet will show up where you can enter your $$ amounts directly..or delete the Supporting Details sheet or perhaps actually use the Supporting Details worksheet ( some people lie to enter each of their prescriptions separately on that worksheet...others just want to use a total.)

1)  Similar issue with the Property Taxes entry  (but be careful..if you entered a property tax payment on the Mortgage/1098 entry, don't double it on the Property Taxes line.  But similar to # 1, try the <Edit<Add Supporting Details or switch to Forms Mode to clear out the Supporting details sheet.
