10-month résumé gap, advice? after 16 years as a delivery driver

I have been out of work for 10 months and worry about the gap. I have been trying to stay organised about it. I am not sure how much to explain. Did anyone get past it?

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.

I listed the volunteering and course under the same dates and kept the explanation to a sentence in the cover letter.
