After you file

In testing this issue, I had no problems changing that part in the Marital Status section of the return, while ensuring I removed the dates as well from previous entries. 

You can do one of two things; but first, I will ask you to follow directives below to assist you in clearing your browser cache to help your browser connection with the software. Sometimes we forget to do this and it piles up and makes online live processes more difficult.

How do I clear my cache (browsing history)?

Then proceed as follows:
  • You can attempt to reconnect to your already started return. 
  • Or delete the return in the "My Account & Returns" section, (garbage pail next to the return) and start a new one.
