Self-employed

I am preparing a joint tax return. I submitted my tax return without issues. I am trying to submit my wife's return and get some error messages or incorrect data showing. #1. I entered bank interest in box 13 of of the T5 slip. Instead of showing this as interest income, the summary page shows the amount under Carrying chaarges, support and others . #2. We are not disabled and I have indicated such at the beginning of the return.  Later in the return is indicates my wife is disabled.  #3. We are not splitting income. Again the page gives us an error message: "Fill out the required information below to calculate your tax on split income." How do i fix these problems, especially problem #1? Do I have to start a new return and how does this merge with my return that has been filed We are retired and split pension income. Thanks, Terry
