We got 1099s from both TD Ameritrade for earlier in 2023 and
the year end 2023 from Schwab. I am noticing significant
discrepancy in Cost Basis with what is showing on LTCG for
Schwab vs Bivio. The Schwab 1099 just came out this week.

Has anyone else seen this?

I am not sure how to adjust in Bivio to try to make the Net
Gain match. These are for transactions where the Basis
will be reported to the IRS.
