Welcome back to Community, @mathpath-school-.
 
You appear to be utilizing QuickBooks Self-Employed, based on your scenario (QBSE). Thus, let me help you with the issue.

First and foremost, let’s perform browser troubleshooting to have the best experience with QuickBooks Self-Employed.

QuickBooks solely computes estimated quarterly federal taxes. It does not account for additional taxes, such as:

• State income taxes (learn more about state self-employment taxes)
• Sales tax (learn more about sales tax in QuickBooks Self-Employed)
• AGI phase-outs and alternative minimum tax (AMT)
• Children's interest
• Medical expenses, stock payouts, and 401(K) draws
• One-time lump-sum distributions
• Special-cases standard deductions (if you're blind, over 65, etc.)
• Tax credits

Please refer to this article for your reference about estimated tax.

It is very important to categorize transactions and it should be matched to a line on your Schedule C so it will show up within your financial reports. See article below:
