I still have not received my tax return it has been 10 weeks. The IRS wanted additional information. How long does this normally take?

It normally takes 3 weeks, however, the IRS does not give an exact amount of time. 

The IRS does not update TurboTax with any information regarding tax refunds or tax payments.  Since it has been 10 weeks, you may want to contact the IRS and inquire about when you should expect your refund.  The phone number for the IRS is 1-800-829-1040. 

Here are two links to track your refund:

Click this link>> https://www.irs.gov/refunds to check the status of your federal return that was submitted to the IRS. 

If you e-filed your tax return you can check the e-file status with this link>>>https://turbotax.intuit.com/tax-tools/efile-status-lookup/

If you chose to pay your TurboTax fees with your refund, the IRS would send your return to the third party that handles the processing of that transaction.  Below is the TurboTax FAQ with their information. https://ttlc.intuit.com/replies/4233182
