I purchased solar in July of 2020, do I have to wait until 2021 to receive the tax credit? I have no line 47 on my 1040 from 2019.

Instructions for form 5695 says to use the "Residential Energy Efficient Property Credit
Limit Worksheet" for Line 14. The first steps says to enter the value on line 47 of your 1040. I  don't have such a line on my completed 1040 that I filled out for 2019 but I haven't started my 2020 return yet as I don't usually do those until the spring time.
