Thanks rjs again for your help.
I am actually planning all these things for this year. We have a house in CA and are buying one in Utah. We want to keep both houses and winter over in CA, and go there in the summer to go to the beach. So we will spend more time in UT and can justify making either state our domicile, as we don’t know how we will like Utah. We will probably buy the house about 1 Sep of this year.
For the 1099s I mentioned like the 1099-R and the W-2. For 2020, CA is listed in block 15 for both. For both block 16 has ‘’state wages, tips, etc’’ with a dollar value in it. So I imagine this value is then reported to CA.
In TurboTax I can say when we moved from one state to another which will then input the number of days into each state return and then it will calculate a ration of wages to each state. I can see how I can split out the income by date as you say but am not sure how I will add this to the state returns when the only options seems to be adding the date moved
