you can't apply. Turbotax selects those who are offered advances and that's after the e-filed return is accepted by the iRS. E-filing won't open until sometime later in Januray. one site says the 24th. do not prepare your return using paystubs. many times the actual W-2 differs which would then require you to amend.
