Thank you for your quick reply.
I bought a 6 month T-bill at auction from the US government through my brokerage account, so the interest was left in the account. I sold it about 5 months later (1 month before maturity). I made $2,510.46 on the sale (final sale price - initial cost of T-bill at auction). Is there a calculation somewhere where I can figure out how much was interest and how much was capital gains?
