IRS website says my refund has been delayed beyond normal processing times, but gives no further info. It was a simple tax return with no itemizations, no charitable contributions, etc. Just W2's and unemployment and 401K distribution that had the required 20% withheld.
The IRS says they send refunds in 21 days for 9 out of 10 efiled returns. The date is an estimate, an educated guess, a rough idea. In other words, it should not be relied on. The IRS can not say how long that other 1 of the 10 will take. All you can do now is, wait. Wait for the pay off of your interest free loan to the government. Did you believe that the IRS is omnipotent, omnibenevolen t and omnisc ient ?

TurboTax gets no information from the IRS after the IRS accepts you return, so no one at TT knows that your refund is delayed or why it may be delayed. If the IRS wants more information from you they will request it by sending a letter. All you can do is watch the IRS refund site----that is your only source of information now.
