Almost all updates to the program after April have to do with "housekeeping or technical issues" and do not affect the returns themselves ... however as a precaution you should :
1) shut off automatic updates once you have filed the return
2) always save a copy of the return and add the current date to the name file ... so if you have to ever return to a prior version you can .... for example JohnSmithReturnAsOf..10/6/19 or JaneDoeReturn.as.filed. 4/15/19 ...ALSO keep a copy of the .taxfile & PDF on a separate storage medium like a thumb drive in case your computer dies
3) only update the program when step 2 is complete
