Asking only for 2019 interest? Account interest was less than $10, and I do not have an 1099-INT form— so I don’t have to report it? Where can I see bond interest?

If bank/financial institution does not send a 1099-INT the interest was not reported to the IRS, so you don't have to add it in.  The bond interest, however, depends on several issues.  If it is from an IRA or 401K (on 1099-R) it is added just like regular income, but in Interest category.  But keep in mind, if the bond is from the state in which you live, it is probably not State taxable.  Hope this helps.

The credit union is not required to send a form if the amount is less than $10. You, however are required to report all income, no matter how small, and regardless of whether you got a form or not.

The IRS allows rounding, so an amount of 49 cents or less rounds to 0 and is not reportable. An amount of more than 49 cents is reportable and taxable.
