Possible to hard delete a mistakenly-entered entity from Section 199A info?

I learned I need to enter passthrough entity Section 199A info differently, but currently my existing K-1 return has an erroneous "sub-entity" showing up every time I try to enter new/different info for the Section 199A details. It seems to have grabbed the first (incorrect) Name of Business and EIN, and continues to use it every time I page back into the form - even after I delete out the entry and click "continue". Is there a way to hard delete this incorrect entity from my existing K-1 or do I have to restart my entire return to get the program to forget that sub-entity?
