Get your taxes done using TurboTax

Dad only had $300 of interest and $5582 of taxable SS benefits (via TT) so does that mean I can't claim him as a dependent?  His total SS was $12527,  and this is for 2015 not 2018.  I am very late filing this.  I have until Oct 15, 2019.  So if I can claim him, do I put his nursing home expense on my schedule A under medical?

Thanks so much for help
