This is total BS!
Turbo tax assume you can only have accounts in CAD. This is not the reality.
If you buy/sell, US stock in a canadian account the transaction (buy and sell) happens from the cash and is converted from the CDN$ at a certain rate.
But for a US account, no conversion occurs, the transaction happen from the US cash.
This is why the box 13 exist on the T5008, we need it,
