Get your taxes done using TurboTax

I've decided to surrender the accounts.  The form I must fill out with the company is requiring me to determine if I should have taxes withheld.  The cost basis for all of the accounts is much greater than the net cash value to be received.  I have the option of withholding no taxes (Federal and State), choosing a certain percentage for just Federal, choosing a certain percentage for just State, or choosing a percentage for both Federal and State.  I'm not sure what to do.  I do not plan on using the money, so it will be available should I need to pull from for next tax season.
