Retirement tax questions

Thanks a lot!!  @ErnieS0 @dmertz 

1. Does the pension startup credit apply to solo 401k? A Single-member LLC with only spouse as W2 employee.

2. The Single-member LLC 's tax will be reported using schedule C. So the max contribution rate for both owner and spouse will be 20%, right?

3. For profit contribution of the spouse, is it calculated as 20% of spouse's W2 wage (BOX 1 in W2) ?

4. For profit contribution of the owner, it will be 20% of net-earnings of self-employment, right?
