Details

Supported transactions:

• "NRA Tax Adj"
• "Credit Interest"
• "NRA Withholding"
• "Short Term Cap Gain"
• "Long Term Cap Gain"
• "Cash Dividend"
• "Buy"
• "Wire Received"
• "Sell" (Not verified)

Not-yet-supported transactions:

• ACH deposit and withdrawal
• Wire withdrawal

I have actual transactions for the supported transactions. "Sell" is an educated guess; I don't have an actual sale. If you could share actual transactions for not-yet-supported ones, please let me know. Thank you.

Duplicate transactions:

As far as I can test, PP will detect and skip duplicate transactions. So it is safe to import overlapping transactions in the future.
