All the answers I have read here appear to refer to catch up payments being made in the same year as the tax year and reported on Form 1099. Isn't the term "catch up" intended to refer to payments made now or in the future for a past time period?
In my case, I left Employer A in September 2021, at which time I had an outstanding 401k loan, due to be paid back before I took a lump sum distribution to rollover my funds from Employer A's 401k plan to Employer B's 401k plan. I did so in 2021. I have been advised by retirement planning professionals that I would have up to October 2022 (or on or before the date I have to pay 2021 tax, if I owe) to make catch up contributions and can only count them toward catch up for 2021, when made on or before filing 2021 taxes (which I am preparing now). I have not been able to find where to list the catch up payments I have made (in 2022), pre-tax through Employer B to count toward the qualified plan loan offset (noted on my 2021 Form 1099-R box 7 (2M)).
