"I do not work " ... that is your problem ... you are not entitled to any of the refund.
To be eligible for any of the refund you had to have income or pay withholding of some kind ...
Look at your column of the 8379 and the instructions for part III here : https://www.irs.gov/pub/irs-pdf/i8379.pdf
To properly determine the amount of tax
owed and overpayment due to each spouse,
an allocation must be made as if each
spouse filed a separate tax return instead of
a joint tax return. So, each spouse must
allocate his or her separate wages,
self-employment income and expenses (and
self-employment tax), and credits such as
education credits, to the spouse who would
have shown the item(s) on his or her
separate return.
Other items that may not clearly belong to
either spouse (for example, a penalty on
early withdrawal of savings from a joint bank
account) would be equally divided.
If you live in a community property state,
follow the instructions below to allocate your
income, expenses, and credits. The IRS will
apply your state's community property laws
based on your allocation if you checked the
“Yes” box on line 5b.
The IRS will figure the amount of any
refund due the injured spouse.
If a deduction or credit would not be
allowed had you filed a separate return, use
the deduction or credit shown on your joint
return and allocate that amount between you
and your spouse. An example of a deduction
that is generally not allowed on a separate
return is the student loan interest deduction.
Examples of credits not allowed on a
separate return are the child and dependent
care credit and the American opportunity
credit.
A similar rule applies to income and
deductions (such as taxable social security
benefits and the IRA deduction) that are
subject to special limits on a separate return.
Use the income and deductions shown on
your joint return and allocate them between
you and your spouse.
