If I received a notice of deficiency (waiver), they included business income from 1099 I didn't claim because they were lost. There were business deductions I didn't claim since I didn't claim any 1099 income, can I now file an amendment to claim the proper deductions? It is about $5k of expenses on $19k of income. I understand I owe the taxes on the non deductible income and the penalty/interest but saving about $1k in federal taxes would be huge. Thank you!
