IRS Transcript Shows $8,136 Refund vs Expected $15k - No Adjustments Visible Despite $8,162 in Total Payments

My transcript shows 'BAL DUE/OVER PYMT USING COMPUTER FIGURES' with a refund amount of $-8,136.00. I was expecting around $15k but my transcript shows TOTAL PAYMENTS and TOTAL PAYMENTS PER COMPUTER both at exactly $8,162.00. The refund amount is showing as $-8,136.00, and both BAL DUE/OVER PYMT USING TP FIG PER COMPUTER and BAL DUE/OVER PYMT USING COMPUTER FIGURES match at $-8,136.00. I've gone through my entire transcript line by line and I'm so confused about why my refund is so much lower than expected. Here's what my transcript shows: SCHEDULE 0012 101 $0.00 SCHEDULE 8812 ADDITIONAL CHILD TAX CREDIT: $0.00 SCHEDULE 8812 ADDITIONAL CHILD TAX CREDIT PER COMPUTER: $0.00 SCHEDULE 8812 ADDITIONAL CHILD TAX CREDIT VERIFIED: $0.00 AMOUNT PAID WITH FORM 4868: $0.00 FORM 2439 REGULATED INVESTMENT COMPANY CREDIT: $0.00 FORM 4136 CREDIT FOR FEDERAL TAX ON FUELS: $0.00 FORM 4136 CREDIT FOR FEDERAL TAX ON FUELS PER COMPUTER: $0.00 HEALTH COVERAGE TX CR: F8885 $0.00 SEC 965 TAX INSTALLMENT: $0.00 SEC 965 TAX LIABILITY: $0.00 PREMIUM TAX CREDIT AMOUNT: $0.00 PREMIUM TAX CREDIT VERIFIED AMOUNT $0.00 PRIMARY NAP FIRST TIME HOME BUYER INSTALLMENT AMT: $0.00 SECONDARY NAP FIRST TIME HOME BUYER INSTALLMENT AMT: $0.00 FIRST TIME HOMEBUYER CREDIT REPAYMENT AMOUNT $0.00 FORM 5405 TOTAL HOMEBUYERS CREDIT REPAYMENT PER COMPUTER $0.00 SMALL EMPLOYER HEALTH INSURANCE PER COMPUTER: $0.00 SMALL EMPLOYER HEALTH INSURANCE PER COMPUTER (2) $0.00 TOTAL OTHER PAYMENTS REFUNDABLE: $0.00 TOTAL PAYMENTS $8,162.00 TOTAL PAYMENTS PER COMPUTER: $8,162.00 Then under Refund or Amount Owed section: REFUND AMOUNT: $-8,136.00 ESTIMATED TAX CREDIT APPLIED TO NEXT YEAR $0.00 ESTIMATED TAX PENALTY: $0.00 TAX ON INCOME LESS STATE REFUND PER COMPUTER $0.00 BAL DUE/OVER PYMT USING TP FIG PER COMPUTER $-8,136.00 BAL DUE/OVER PYMT USING COMPUTER FIGURES: $-8,136.00 FORM 8888 TOTAL REFUND PER COMPUTER: $0.00 There's nothing in the Third Party Designee section except: THIRD PARTY DESIGNEE ID NUMBER: AUTHORIZATION INDICATOR: 0 THIRD PARTY DESIGNEE NAME: I have a Schedule C business but that doesn't explain the discrepancy. What I don't understand is where the approximately $7,000 difference between my expected refund and actual refund is coming from. There are literally zero values on every line that might show adjustments or credits being reduced. Has anyone experienced something similar or know what might be causing this? Why would there be such a big difference between my expected refund of around $15k and the actual $8,136.00 when there are no obvious offsets or adjustments showing on the transcript?
