Apols - not sure I understand what you are looking for.
I thought my first message was clear (Price is 131-23 per 100 face amount, so each $100,000 contract in this case has a value of $131,718.75 in decimals) - that is 131-23 * 1000 obvs.
You previously said Since you mentioned the 2.75% coupon, the 131-23 must be the price at maturity since the yield is lower than coupon
Bonds mature at 100. Futures don't mature - they expire. It may help to understand what happens when you buy and hold a future to expiry.
Let's say you buy one future ($100,000 face amount) and still own it at expiry in June. If that is the case, you will have to buy and pay for $100,000 face amount of actual treasury bonds. When you buy the future, you don't know which bond you are going to get, though it is likely to be the CTD issue - for the June contract, currently the 2.75% Feb 2028.
The amount you will pay for that bond depends on the price of the future at expiry. The price of the future could be anything, but let's imagine the market has rallied a bit and futures are at 133-00 on expiry in June.
To receive your $100,000 face amount of the 2.75% Feb 2028 bond that is going to be delivered to you under the one futures contract that you own, you will pay: the futures price at expiry (133-00) * 1000 * the conversion factor of the 2.75% Feb 2028 bond (0.8272), plus the accrued interest on the bond (1025.55). The total is around $111,043.
You can rearrange that equation for an easy proxy to work out theoretical futures fair value: take the current price of the CTD bond 2.75% Feb 2028, adjust for carry, and divide the result by the conversion factor.
Current bond price is $109.5937, carry is -0.578, CF is 0.8272. That gives 131.79 fair value vs actual futures level of 131.70
hope that is helpful
