Confused about dryer sheets
It was many years back but, as I recall, I had to go with a check. Same when I rolled a portion of the TSP over to Schwab (so I could write checks to charities with the RMDs to get top of the line tax deductions). The TSP has some excellent funds but they are a PITA for withdrawals, roll overs, and roll ins.
It appears a check is still the only way to transfer IRA funds into TSP. Mail check to them and can take up to two weeks for the deposit to show in the account.
Official TSP reply:
The TSP has never offered the option for participants to transfer funds into their TSP accounts electronically. TSP transfers are documented by the TSP's recordkeeping system but held by the United States Department of the Treasury (Treasury). Please be aware that, while the Treasury does issue other types of TSP disbursements by electronic funds transfer (i.e., single payments, installment payments, and loans issued directly to participants from the TSP), the Treasury will not issue TSP transfers to or from IRAs at designated financial institutions or eligible employer plans by electronic funds transfer or wire transfer. The TSP is not a financial institution and does not have routing numbers for wire transfer. Consequently, all IRA and eligible employer plan transfer payments must be received by check.
