I donated a table to someone who was getting back on their feet. It was through Navajo nation here in az. Is there a way I can add that in? I don't know the charity name.

If the donation was not to a recognized charity you can’t deduct it.

No,  “Contributions must be made to qualified organizations to be deductible.  

A qualified organization is one that that has been granted tax-exempt status by the IRS and is eligible to receive tax-deductible charitable contributions. Examples of qualified charitable organizations: Churches, mosques, synagogues, temples, and other religious organizations
