We made a change last fall so that Tax Free is not shown on the income graph mainly for Roth Conversions. A conversion from qualified to tax free should not show as income as it is really a roll over. This is a very important technique so we changed the program.
For a home sale, if using a cash infusion, the Tax rate to apply being 0% makes it Tax Free.The last column should be set to Taxable because it is received into a checking account not directly into a Roth IRA.
If you do it that way you WILL see the home sale show up on the retirement graph.
