Dropped my CSV into ChatGPT with the following prompt and the output file worked:

``` Modify this csv to match this format: Follow these steps to import your account activities from a CSV file:

Ensure your CSV file is in the correct format. Columns should include Date, Symbol, Quantity, Activity Type, Unit Price, Currency, and Fee. Click the 'Import' button and select your CSV file. Review the imported activities before confirming. Supported Activity Types:

Except it couldn't find the symbol `BRK/B`, `BRK.B` or `BRKB`.

I would just switch brokerages. Not just for the csv issue, but their platform has taken a shitter since acquiring TDA.

Are there any you can recommend?

have had no issues with IBKR since switching last year. There was a recent “crash” (the Japanese stock sell off?) that caused a massive influx of retail trading and dark pool trading. At market open on Monday, SCHW account with 401K was not accessible. But IBKR was up and running.
