Retirement tax questions

Mine is a solo 401k with eTrade; they are my plan administrator and issue all the tax forms.  They just don't seem to know what they are doing.  First they issued a 2018 5498, which they acknowledged was wrong.  Then after months and months of saying it was in process, they finally issued this 2018 1099-R last week which is also wrong.  I know they were "required" to issue one by Jan 31, 2019, but it's not like I can make them do this right.  I have contacted them dozens of times and they just seem to pass the information along to someone else.  Maybe it's outsourced but I don't know who it's outsourced to.
