My wife and I filled together, but i was wondering if there was a way to see how much we each contributed to the total refund?

On a joint tax return the refund is based on your combined income and the combined amount of tax withheld during the year. It's not partly your refund and partly your wife's refund. It's your joint refund. There is really no way to separate it and say that each of you contributed a certain amount.

this is a method that you may want to consider.     split your income and deductions.

so the total for both equals the taxable income on the return 

take yours and divide by the taxable income.

multiply the fraction from above by the tax before credits. 

subtract your share of credits

add your share of additional taxes

subtract your withholding

subtract your share of estimated tax payments

the result could be your share of taxes is actually higher than the amount you paid in

do same for spouse

just to make sure the results for both should equal the refund

basically this is how professional software does it, but judgement is called for in splitting some items such as interest income from a joint account  and itemized deductions.  professional software will split the items 50/50 when joint is indicated.   TT does not have this feature.
