The form and section names correspond to different incomes as outlined below:
| 1099-INT import supported | Interest income |
| 1099-DIV import supported | Dividends and Distributions |
| 1099-B import supported | Proceeds from broker and barter exchange transactions (e.g. stock sales) |
| 1099-DA | Digital asset proceeds from broker transactions (e.g. crypto sales) |
| 1099-MISC import supported | Miscellaneous income |
| 1099-OID | Original Issue Discount income |
You may have all of these on your consolidated 1099, or only the ones that apply to you. If you have a section that has $0 for all amounts, that means you didn't have that income, but the financial institution prints it for all accounts.
