How much did I make last year

[mesquitebean]

There's no way anyone in a user forum can know that.

What are you doing?   What is the context of your question?   Are you preparing a 2018 return and asking something about the 2018 tax year?

Or are you trying to efile a 2018 return, and it's asking you to enter your 2017 AGI to verify??    If so, we can tell you how to find your 2017 AGI.
