Apologies for any confusion caused. The process I described earlier was a general explanation of consolidating UTXOs, but I didn't take into account the specific scenario you mentioned.
In your scenario, if you have three separate transactions (A, B, and C) totaling $99 and you want to consolidate them to a new address, the resulting balance in the new address should still be $99.
To achieve this consolidation, you would create a new transaction that uses all three transactions (A + B + C) as inputs and sends the funds to your desired address. The output of this transaction should indeed be $99.
Thank you for bringing up this clarification. Remember that it's always essential to double-check details when performing actual Bitcoin transactions or seek guidance from reliable sources or experts in the field.
