Box 10 is bad in year 2021 !!

Hi everyone,  in year 2021 you could potentially get back 50 % of your childcare that you put on form 2441. 

however if you took off the money from income in box 10 of your W2 then all it does It make your income lower by that amount but you loose out on getting 50 % back (fully refundable).

Is there any solution how to put it back in your income to gain more refundable amount?
