I have shares in a company that went bankrupt (MSLPQ.) I lost 100% of my investment. The issue is that the shares still show up in my portfolio. My broker (Fidelity) told me they can't do anything with the shares since the company has been de-listed. I assume I can't declare the loss because technically I still own the shares.
Any guidance? The portfolio listing is mostly just annoying and I can deal with that, but I really would like to declare the loss for 2025.
