IHSS Untaxed Income Causes My CA Refund to go UP

Hello,

 

Normally I don't enter my W-2 for untaxed IHSS income ($0 in box 1). But every few years I enter it to see if it changes my tax refund. Tax code is complicated and you never know what could be new. As many have suggested I enter $1 for box 1 so I can e-file. I do pay Social Security and Medicare taxers. When I enter the W2 my federal refund doesn't change. However my CA refund goes up by the amount I paid in Social Security and Medicare taxes. 

 

Is this normal? This seems like a bug in Turbo Tax. I'm most likely going to delete the W2.

 

Thanks
