Investors & landlords

I went through and selected to go through the Cost Basis flow as noted, but I am getting an error each time once I input the data (either manually entering the cost basis or entering the purchase price method).

Note: I am not having internet connection issues. This is specific to this workflow. I can go back and every other section of TurboTax works just fine. I have now tried to go through this workflow over the course of a full day and this error only occurs after trying to finish the cost basis workflow for the Small Business Stock sale.
