Non-Dividend Distribution - practical cost basis question

[DXY2021]

Hello - just had a practical question on non-dividend distributions please - i know these are a return of capital and lower your cost basis

My question - do most investment firms keep track of these when tracking the cost basis of a security?  let's say it is a recent stock purchase (so its covered and cost basis is reported)  If i sell this 10 years from now and there are 10 years of non-dividend distributions, will these companies track this in basis, or do i have to keep a manual spreadsheet of these and adjust for it when i eventually sell the security

just trying to plan ahead for the best way to track them, IF i even need to do so - i can understand doing this if its an old non-covered security,etc

thanks for your help

DXY2021,

I don't know about other big investment firms, but my Wells Fargo account(s) do keep track of return of capital and show basis adjustments in my statements.  That doesn't stop me from maintaining my own records which I started keeping back in the 80's.
