I just completed my 2025 tax return only to discover days later that I forgot to submit 2 1099-DIVs (from the same company) the last two years (2024, 2025). I filled out an amended tax return and I don't owe anything on the federal level. Do I still send in the amended federal tax return or should I only send in state, where I do owe? I have not heard from the IRS regarding last year's omission (this year's hasn't been processed). Sorry if this is a dumb question.
