I am assuming part year, moving from one to the other. Use Ctrl + E to allocate gross receipts between TN and CA (two lines, one for each state). Depending on how much work you want to do, do the same with each expense item OR just cheat and make a few of the $1 for one of the two states to make the total shake out. Alternatively use screen 51 to make a modification for CA schedule CA to make it work out. TN has a HALL tax and the Schedule C should not come into play.
