Final 5500 after entire solo 401k rolled over into SEP IRA

[NJ Harrington]

Solo 401k rolls all money in the 401k into a SEP IRA n 2019.  1099R issued, but 401k administrators does not file a Final Form 5500.  Does anyone know how to correct this now?

1.  Confirm plan was actually terminated by company action, like a resolution.  So that 2019 is really the last year of the plan, rather than it continuing to exist with $0 assets.

2.   https://www.irs.gov/retirement-plans/penalty-relief-program-for-form-5500-ez-late-filers has the steps for what/how to file and pay the much cheaper penalty.
