Solve for X:

2019 -- return not yet filed.

2018 -- balance due paid.

Social Security -- Yes, direct deposit since 2018. 

This client received a check, based on 2018 income.  First (and probably last) year his AGI exceeded $75K.  I just watched a seminar in which it was stated that IRS has a "one check only" policy for the rest of the year.  If you received $200 before filing 2019, you're not going to get the other $1,000 before filing your 2020 return.  Same thing, for unfiled returns from parents of babies (twins, triplets, etc.) born in 2019.
