Just confirming: Line 22 of Schedule E Worksheet shows a loss?
While ProSeries does have a significant error in that regard, I'm not quite seeing why it is being applied to your situation (and I can't recreate it, unless you entered the insurance and supplies on weird lines).
'Pure' rental expenses (that have no personal use) and mortgage interest and real estate taxes CAN potentially create a loss. However, ProSeries' error that they have ignored since 2018 is that mortgage interest and real estate tax can only create a loss if otherwise allowable - in other words, if you Itemize on Schedule A (for the most part). That is what the IRS and Tax Court changed/clarified, and what Intuit has ignored since 2018.
Entering on line 11 (management fees) - that is treated as pure rental expense. If it is partially applicable to personal use, enter it on a different line. Look at column (d) of the Schedule E Worksheet. If it is a "gray" box, that is an expense that ProSeries will potentially allow a loss, such as advertising, commissions, management fees, and other expenses.
Except for mortgage interest and real estate tax, don't enter a 'shared' rental expense (that could have some personal element) on any of those lines that have a gray box in column (d).
Getting back to your problem, even IF you were Itemizing, I'm not seeing how those amounts on the gray-box lines are adding up to an amount larger than the $6885 of gross rent. In other words, unfortunately, I'm unsure why it is doing that.
Maybe post some screenshots of the entire Schedule E Worksheet?
