Was a 2018 8606 included with your 2018 tax return with the contribution on line 1?
You said "including the explanatory statement" . Was that in the recharacterization interview? If so, and a 2018 8606 was included that had the non-delectable Traditional IRA contribution on line 1, then this might be an error that lead to the correct result anyway.
