I started a small side business in 2019 and failed to report my income. Im am now filing an amended return and it states im going to be getting more money back. I also filed a w2 in 2019. My question is. I have the 2 written contracts for the jobs i did. 1 is for $2400 the other is for $1200. I have bank statements for the money i recieved. 1 being $2400. The other only totals $740 for the $1200 dollar job due to me having to buy materials for it. I no longer have the material receipts. So do i report the whole $1200 or just the $740 on my bank statement?? Also what would be needed for proof just the bank statements and hand written contracts would that be sufficient if they need proof. Thank you for any advice
