I need to change to tax free

[SteamTrain]

First get back into  your 2017 online tax return.  (not on the Home page after login....continue into it)

1) lower- Left side of the screen...click to the left side of the "Tax Tools" text selection.

2)  then select "Clear and Start Over" from the drop-down expansion below Tax Tools

......that should allow you to restart and select a different product.....(at least that's where it was done last year...but I'm not messing up mine by trying it myself)
