TurboTax does not support deferring gain by investing in Qualified Opportunity Zones. There is no way to enter it. If you want to defer capital gain by investing in a Qualified Opportunity Zone, you cannot use TurboTax to file your tax return.

Bummer,

Even if TurboTax doesn't support form 8997 to keep track of the OZ investments over the years, it should still provide a mechanism to allow a user to add the single line to form 8949 with code "Z" in column (f), then OZ deferral amount in column (g) as a negative number, putting the OZ EIN in column (a), the OZ date in column (b), and leaving columns (c), (d), and (e) blank. This is straight out of IRS instructions for form 8949.  

This inability of TurboTax "Premium(sic)" to handle this will unfortunately cause this VERY long-term TT user to switch to another platform.   

Sad, very sad.
