removed money from 401K investment and returned a portion of it within 30 days

in 2020 removed 20,000 from 401 k investment at Merill Lynch.  I received a 1099R showing that.  In less than than 30 days 10,000 was returned to this account.  Where do I show the return of the 10,000 in my turbo tax preparation?  judy and steve myers
