Forgot to mention:I've made Roth contributions at Schwab from this settlement account many times. Most recently a few days ago. It's a straightforward process online:
1) From the "Move Money" menu select "Online Transfer"
2) Select the From and To accounts.
3) If the To account is a Roth IRA it will display current and previous year contributions and ask for the tax year to apply for this transfer
4) Supply tax year, amount, transfer frequency, and transfer date
5) Funds show up immediately in the Roth
Some call it the sweep, and it is cash in my taxable brokerage. I'm not aware of a way to auto-invest that into a money market fund.Yes, it's the default fund that Schwab uses when money is moved to or from the account or when funds are liquidated.
+1 Though it is odd that Roth conversions can be made in kind but that Roth contributions must be in cash. Cie la vie.That was correct. It sounds like contribution needs to be cash as mentioned by SecondCor521 above.
