Hello @Panther60
If you checked "I have no information in the other boxes" and imported a form with zero's, it may loop to "Needs Review." You may need to delete all the zero's and the "Needs Review" should go away. TurboTax counts zero's as content so this could cause this issue.
Additionally, if you can Click on Review and it will tell you what forms you are missing. Some forms may not be available yet so you cannot file. The IRS has to finalize a number of forms and then approve the finalized forms in the TurboTax software.
Please see this Turbo Tax FAQ on the availability of IRS forms. Federal Individual Form Availability Federal Forms.
Hope this helps.
Thank you
