If I remove excess hsa contribution and interest is few cents to few dollars, do I need to worry? Do I claim excess hsa contribution as income?

If I remove excess hsa contribution, 1. how do I calculate the interest?   Should it start at the latest contribution date (or approx. the date that would incur the excess)?  If interest is few cents to few dollars, do I need to worry? Do I claim excess hsa contribution as Other income?
