Thank you @Mike9241 . well it was precious metals investment, so collectibles. No negligence to pursue; he wouldn't know, nor did I, as broker did not send out 1099. Itemized. Extended. Well unless any other thoughts, I guess I can only revise for 2018 interest, foregoing nearly $150k of accumulated interest in what amounted to a very large capital loss as it was in 2018/2019.
Thanks again for your input.
