Thank you so much!! Will take a step back and restart with the water and sponge.  Definitely got too aggressive and damaged the section were it looks like a patch was made (as there is a crushed dent there that I know we didn't do!).  Plan to try to tackle the glue and then run out for some Kilz.  "Fun" start to the new year.  🙄  Don't think my second career will be home renovation (although flooring isn't so bad...).
