Retirement tax questions

I missed the statement:

 

"However, I did do a Traditional => Roth conversion in March 2019 before I withdrew it all as excess contribution."

 

Where was the excess contribution?   In the original Traditional IRA prior to conversion?    Why was it excess - did you not have taxable compensation to support the contribution?
