Adding Manual Transactions

I am having issues manually reporting a loss transaction to reflect on my tax form. What is the proper way to manually process a sold transaction showing a loss but still reflect the correct amount of coins in my wallet?

If I sell my crypto to USD I am unable to report it in a negative value? I have processed sale from crypto to USD and then report a transaction showing USD as a loss?

Is there a way to report the original crypto transaction as a dollar value loss?

Instead of putting the sell, you can just create a withdraw of the crypto and classify it as a loss. Accointing will then calculate what the USD value was at the time.

Thank you for the recommendation.

After doing it this way, it does assign the loss but the dollar values do not match correctly.

Is there a way to be specific with these manual transactions as I know the exact amounts?
