Is this option available when amending a return? (1040 - year 2019)

I turned in my Fed return 2019 on time last year.  But I only now finished my 2018 which I chose the option to Apply all 2018 returns to 2019.   But I only need to amend 2019 to show those funds applied..plus add Cap loss carryover.   

Question:  When selecting 2019 Amend (online) how do i get it to see my "Line 21 Applied to your 2019 estimated Tax" from the 2018 return?  

Thank you very much for any assistance community.
