Registration and entry error

After the last update when entering the program a screen came up showing my registration.  I clicked on it and the application came up fine.  Today started up Turbotax on my mac and same screen came up.  I clicked on it and my data came up but now says I have registered on two computers when I am on the same original computer.  Need to install on another computer but afraid will use up computer count if have to click on registration each time.  Also entered a 1099 R.  Thought I  had entered everything correctly.  However when  time to check it said taxable box different than gross.  I changed it to proper number but Turbotax still showed erroneous number.  Had to delete 1099R and reenter.
