For taxpayers that have both a Roth IRA based on their own earnings and an inherited Roth IRA from a grandparent, why does the IRA Info worksheet reduce the Roth IRA basis of the taxpayer's own IRA?  An inherited IRA has its own distribution rules separate and distinct from the rules for distributions from ones' own Roth IRA.  Distributions from the inherited IRA should have no impact on the carryover basis of a "regular" Roth IRA.

On the 1099R worksheet, the third and fourth checkboxes under "Inherited IRA" should be programmed to allow for this situation.  The 2019 and prior ProSeries programs handled this correctly based on the checkboxes, but not 2020!
