Get your taxes done using TurboTax

I have done all the work by using my download version for 2019 & 20. I just am confused by what it wants me to put on line H (step 5 of applying the credit) it says to put the calculated difference in tax paid vs what should have been paid if no overpayment was made on line E.  I just need to know what it means by adjusted amount of tax paid for line H.  

Thank you
