I have only used to fill and print out a 1099-misc. After reading the general instructions of how to report my DE 542 information and what I needed to understand. I was sold on PDFffiller.com
I am a little confused on the detail of how and what I want to do etc.
Once I have some practice getting around my PDFfiller site I'll answer you follow up survey. P.S. * I am an old lady and I don't really know my way around a computer. Thinking about it. I felt your site was elder friendly. It is importune to keep it simple now that older senior citizens are force to get online to bank etc. Thank You

I like the program a lot. You recently changed the format a little. When I want to save a document to my computer, I can't tell it where to save it; it automatically saves it to my downloads, which I do not like. Before you changed the format, I was able to save a PDF completed document to whatever file I needed to on my computer. I would like to be able to do that again.
