Retirement tax questions

*Update: TurboTax IS telling me that I've over-contributed $200 to my Solo 401k plans and need to take out the excess contributions; however, subtracting $200 from $18,200 (total contributed across Solo 401k plans for 2021) still doesn't net to the $17,395 'max.' Self-Employed Retirement Deduction allowed stated by TurboTax in the earlier step.

 

So, I'm not sure if I should only take out $200 excess contributions or $18,200-$17,395 = $805 in excess contributions?
