I'm doing a one-time RMD to cover all my IRAs into my Schwab-1 brokerage account. I read the cheat sheet post from Jim Harmon, but it looks like that won't work with a brokerage account, as "Deposit" is not a transaction type. The corresponding type is xIn and splits don't exist.
How do I accomplish getting an RMD into the brokerage account while accounting for withholding?
