Thanks @rjs
- one entry for one entity 1e is slightly lower 46.78 from additional information "original basis: 47.48" field, not much to gain from increasing the basis (hardly ~$0.7 gain) ...
- another entry 1e is higher 4,000.24 than "Original Basis: 3,800.56" so some difference
However now I recollect I had wash sale for 2nd one few years ago, so option c of using 1e makes perfect sense now.
For #1, going over 1099 again found the reason, saw that the stock had a NonDividend distribution (under "Return of Capital and Liquidations" section of the 1099 document) of amount 0.70 (3/30), which tallies with the difference in basis. Am guessing I got ordinary dividend of $1.38 on 3/30 and then I sold the stock on 4/20 (<60/61 days - don't know ex-div date), so 'guess' something to do with that (not sure if this is how they do it, reducing basis OR <60 day rule is for qualified vs. non-qualified dividend - to research it out some other time)
