Cost Basis v. Adj Cost Basis for Bonds

[msindc1]

Folks:

Client's 1099-B reports proceeds ($10,000) and cost ($10,000).  But at the end it also reports realized gain or loss reiterating the proceeds numbers but stating $10,890.50 for cost basis and $10,000 for Adjusted.

I'm confused--which number do I use?  What is this telling me?

Use Adjusted.

It's been adjusted for premium/discount amortization over the years.

@sjrcpa Asking here since you could be lurking.  Thanks for your time.

In screen 11 (code 37) is an input for "Amortizable bond premium for tax-exempt bonds". In contrast, the instruction from using F1 says to "enter amounts only attributable to taxable interest only."  Do you see a way to reconcile these 2 things?

I figured it out.  No response necessary.
