Hello - I have resolved this problem by myself. I have found function "contrast" on the top of screen and I was able to adjust the size of my fonts. When I have changed the size to "smaller", I was able to see full payment details screen , which enabled me to enter my CC details. When that had happened, I have completed the TURBOTAX cycle successfully within minutes (that is, sending data to CRA and saving both my wife's and my data to my C disk).
