I did set up an account and it informs me that the return has not been processed yet so I will see it when it is processed, which it says is within 21 days of e-filing. It shows balances etc. One can also set it up to receive notification of receiving certain notices from IRS so one can log in and see them without waiting for snail mail to deliver them (maybe). But it's not applicable to all notices. Cool to have the account.
