How to track tax return ? I submitted Turbotax generated file to IRS through mail. However, if am tracking in IRS it shows invalid details. Any leads from Turbo Tax?

Mailed returns are taking a long time this year.  Like 6 months or more.  And the IRS Where's my refund isn't always updated.  You have to keep waiting.

unless you use a method where you can track delivery of your return, there is no info until the IRS enters it into its system,
