When manually inputting proceeds and cost basis, I selected "short term did not receive 1099-B form."
Generally, capital gains are taxed according to how long you've held a particular asset – known as the holding period. Profits you make from selling assets you’ve held for a year or less are called short-term capital gains. Alternatively, gains from assets you’ve held for longer than a year are known as long-term capital gains. Typically, there are specific rules and different tax rates applied to short-term and long-term capital gains. In general, you will pay less in taxes on long-term capital gains than you will on short-term capital gains.
If you just have a few transactions enter them manually. It sounds like they are short term (held less than 1 year) so they will be taxed as ordinary income.
if you did not receive a 1099-B and you are certain that you will not get it at the end of February ( the deadline for the broker)
you must set your sales category to C or F.
Recommend you check with your broker to find out where is your 1099-B.
