This is what it states, "Cost basis is not applicable to tax-deferred accounts, including 529 and retirement accounts, or money market funds." 

They did email me a year by year account of transactions which contain Dividends and Capital Gains. This goes back from now to 2003. That's like having a road map without a destination. This account was handled by Wells Fargo Advisers. I have asked them for information but, for whatever reason, they have not responded yet. I don't know if they are obligated to provide this information. American Funds said they do not supply this. There should be a simple rule.

Thank you for responding. 

(I don't know if I am responding twice but here goes)

if you sold in 2019, what kind of tax form did they send you? 1099-B? 1099-R? nothing?

if you are 74, did they remind you to take your RMD, which would mean this is a IRA.

1099 B from Wells Fargo. Lists # of shares, Proceeds, and no Cost Basis or anything else. Tells me to report it on Form 8949 Part 1 with Box B or Part II with Box E checked. 

RMD is taken from another account.
