True.
Check your statement carefully, though, how much was withheld from the check you got?
IRS rules, pre-Cares, require that the fiduciary withhold 20% for the IRS.
So, liquidate, as you did, and you have to add all that you got (80% of total) plus the 20% that was withheld to avoid paying taxes on the distribution. Sure, you’ve deferred taxes under Cares, and didn’t get hit with the penalty, but that tax bill is coming unless you roll over 100% of the value of the 401(k).
Which means, you’re going to have to contribute in a lot more than you got in your check to your Roth.
It’s a trap, and people fall into it all the time. That’s why a direct roll over from fiduciary to fiduciary is the recommended course for most folks.
