Excessive Roth Contribution

I contributed $6000 to my Roth for 2019.  I have a MAGI of 193,200, which puts me over the threshold for eligibility for Roth contributions.  

 

By my calculations, I need to return $120, plus the earnings, and report the earnings as income.

 

But if the earnings are income, doesn't that affect my MAGI again?  And wouldn't that further affect my Roth eligibility? How is this untangled?  I don't see in the IRS instructions where it says not to include retirement distributions in MAGI.
