TT Installation Issues

[Scott88888888]

I erroneously installed the desktop version of TurboTax Home & Business to handle my mother's taxes.   It was the wrong product so now I want to remove it.   I can't find a way to delete the H&B install on my Mac.   Additionally, I now want to install Premier for my own taxes.   Install will not let me replace H&B with Premier despite choosing the Premier option on the download and choosing the option to replace the files.  

What am I supposed to do?
