You can buy it as a CD or a download to get Forms entry (very similar to ProSeries), you just don't want the Online version. You cant transfer your PS files into TT though, so youd be stuck entering any carryovers manually.

This is a link to the desktop version

Its on Preorder now until 2020 is released.
