Deductions & credits

Thank you for the previous answers to my problem. I am working on the depreciation amendments of 2018 and 2019.  I have gotten 2018 figured out and ready to submit, but as I work on 2019 it is pulling the information from the original 2018 which is showing my business with a loss. In the amended form I have a profit in 2018. Anyway when the Qualified Business Income deduction summary comes up in 2019 amended form it is showing a "loss carry forward from 2018" and making the QBI coming out smaller. I don't really care about the QBI but don't want to mess up the amended 2019. How can I go in and change the information  the program is using from 2018 to the amended amounts? Also as I do the 2020 I am assuming the same thing will happen so what is the best way to continue on with 2020 and not have the original 2019 information automatically added?
