I found my credit report. How could I use it to calculate AGI 2018?
I don't have 2019 (or 2018) return.
A credit report cannot be used for the Adjusted Gross Income on a US Federal Tax Return.
See this IRS website for the definition of an AGI - https://www.irs.gov/e-file-providers/definition-of-adjusted-gross-income
