When you save or print a copy of the return Including all worksheets, you should find the Sch D computation included in the worksheets.
IRS did have an error in their tax computation with capital gains on returns that were filed before mid March resulting in letters being sent out recently with the adjustment. Mid-March IRS informed tax software providers of their error and the tax programs were able to be updated for the correct computation, so this may be you situation.
