In 2017 I used "ufile online". This year I bought "ufile for windows" (purchased online)and downloaded it. 1.The programme would not carry forward data from last year. 2.When I went to file my taxes , the programme asked if I was ready to pay and would not advance. I went to "my account" page at ufile, and the green "paid" button dropped down from 2017 to 2016 How can I file without paying twice?
