Retirement tax questions

Thanks.  To clarify, I took 10% ($1000) of my $10,000 RMD in 2018 (and the remaining 90% in 2019).  My understanding, which may be incorrect, was that my RMD in 2018  was anything I wanted from 0% to 100% of my total RMD.  So would it make sense to keep the form 5329, and enter $1000 as my RMD?  Then, for the 2019 form my RMD would be roughly $9k + $10k.
