The IRS requires companies to fill out 1099misc (miscellaneous income) forms for people or businesses that are paid $600 or more in the year usually for services (cutting grass, construction jobs, etc). You must report any of the income on 1099's.
With 1099int (interest income), that is usually from a bank or investment company and it reports the interest that you have accrued on your bank accounts. Most banks will not send out 1099int forms unless you have made more than $10 in interest for the year.
If you want to be "Dudley Do-Right" you can go down to the bank and they will print one that shows you made $1.04 in the year, but I can guarantee you that the IRS will not come after you for not reporting less than $10, they have much bigger fish to fry. Plus taxes they would have gotten out of your $1.04 wouldn't be worth the postage they sent your warning letter with.
1099Div (Dividend Income) is usually from investment companies. It report the income from the sale of stocks, or if you currently own stocks that pay dividends, then they report how much you recieved from the stocks. So if you don't own stock, don't worry too much about these.
