difference between W2 and 1099-R

I am 65, retired and just finishing my State taxes. I did not work my summer job last year, which usually amounts to about $7,000.00 and a W-2 form, but not this year. I only have 1099-R for my pension and a SSA-1099, for Social Security.

Should I be concerned?

I usually pay a small amount, $50 - 100. This year, I had a refund of $50.00, which I divvied   to various state charities listed on the form. 

Again, my concern is that filed correctly based on TurboTax's guide?

Thank you
