How to report Roth earnings after early withdrawal of all 2020 contributions?

While doing my taxes this year I discovered I was barely over the MAGI limit for making Roth contributions during 2020.  I withdrew all $5500 contributions for 2020 and moved them to my taxable account.  I am left with $1089 of earnings that I assume need to accounted for, taxed, and likely penalized.  How and where do I report this figure?  My financial institution's rep said I should file form 5329 for the 2020 earning and that I would not be receiving any tax forms from them until next year (which would not need to be filed because I will have taken care of it this year).

 

I am struggling to see where to enter this information or what question to answer that correctly accounts for that $1089 earnings.  Any guidance would be greatly appreciated.
