Has anyone else experienced very long delayed refund times from irs this year through Turbo Tax ? I e-filed and its been over weeks and still no refund.

Yes millions are waiting months.  Turbo Tax only gives you an estimated date. The IRS usually pays most refunds within 21 days. But these are not normal times. This year is taking the IRS longer to send the refunds. There are millions more people filing returns to get the Stimulus payment.
