I am attempting to search my bank (M&T bank) for the 1099-INT entry but by bank is not showing up. I've tried typing the full and abbreviated names.

If this does not work, you may need to manually enter your 1099-INT.  

Thank you. I would like to enter manually but do not have a 1099 due to the interest being so small. Do you have any suggestions?

You can contact your financial institution directly and request they provide you your 1099.
