I was able to replicate your situation in TurboTax Home and Business. Use Forms mode (icon top right in blue bar) to enter a workaround.
On the "Asset Entry [name]" form titled Form 8829 Asset Entry Worksheet, Section 199A (QBI Deduction Attributes) section at bottom of form, first line is Unadjusted Basis Immediately After Acquisition (UBIA) for this asset, and will be populated with the UBIA for your home office.
Ostensibly, that number should “flow” to Schedule C, Qualified Business Income Deduction Smart Worksheet (after line 48), line J1. But, line J1 is blank, i.e., the UBIA of the home office does not “flow” from Form 8829 Asset Entry Worksheet, Section 199A (QBI Deduction Attributes) section.
If the amount of the home office UBIA from the Form 8829 Asset Entry Worksheet(s) is entered as an “adjustment” on line J2 of the Schedule C, Qualified Business Income Deduction Smart Worksheet, the income limitation calculation on the QBI Component [name] form includes the UBIA of the home office.
