I am having the same problem. I am trying to input my spouse's 1099-NEC and it keeps asking for me to review it and I've gone over it multiple times. 

The problem is that the actual 1099-NEC worksheet doesn't give you the option of linking the 1099 to either Sched C or Sched F. Hopefully, Turbotax online has a solution to this problem soon.

The issue has been submitted and is currently under investigation.  Please click on the following link and sign up for an email notification when it's fixed.

Why am I not able to link my 1099-NEC

Thank You for your patience

Beginning with the 2020 tax year, the IRS will require business taxpayers to report nonemployee compensation on the new Form 1099-NEC instead of on Form 1099-MISC. Businesses will need to use this form if they made payments totaling $600 or more to a nonemployee, such as an independent contractor.  This was done to help clarify the separate filing deadlines on Form 1099-MISC and the new 1099-NEC form will be used starting with the 2020 tax year.

So, if this an error, how do I get past it to complete e-filing?

Some TurboTax customers were experiencing an issue linking their 1099-NEC.   To remove this error and e-file your return:

1. Sign in or continue your TurboTax return.
2. Click on the Review tab and proceed through the screens until you see a screen titled "Delete Confirmation" for Form 1099-NEC.
3. Select Yes to delete the form. Delete each 1099-NEC that is being prompted.
4. After you have confirmed the deletion of these forms, please return to your business income to confirm all the 1099-NEC's you have received are entered.
5. Once you have confirmed this, return to the Review tab and complete filing your return.   @laura12870
