I have yearly 1099s for royalties I recieve for my late father's work. I do not have expenses for these earnings.Can I deduct anything?

These are reported as investment income from property you own since you did not create the music that generates the royalties, therefore, it is not Schedule C self-employment Income. 

If you did not have any expenses, there is not anything to deduct.

With your return open, search for 1099-MISC and select the Jump to link in the search results.

When you enter your 1099-MISC, enter the income in box 2 - Royalties. On the following screen, choose the source of your royalty income:

• Investment income from property you own – This includes natural resources extracted from your property by a third party who leases your property, as well as royalties from intellectual property that you didn't create yourself. This gets reported on Schedule E.
