Is the 1099-Div I received for sale of company stock correct? How to take into account basis, length of time asset was held?

The company I used to work for had a buyback and I sold my shares which I've held for 19 years.  The basis was $25k and I received a total of $50k in the buyback.  They infrequently do buybacks. Today I received a 1099-Div that has the full $50k in box 1a (Total Ordinary Dividend).   

 

Based on these factors:

 

1) Does it make sense that I would get a 1099-Div instead of a 1099-B?

 

2)  If the 1099-Div is correct, should the entire sale be reported as an ordinary dividend?  Or should I be asking the company to use field 9 Cash Liquidation distributions or other fields on the form?

 

3)  Again if 1099-Div is correct, how do I reflect that there's a $25k basis so I should be taxed on the remaining $25k at long-term capital gain rates?
