Again, all I can suggest is to review the Keogh, SEP and SIMPLE Contributions Worksheet to see what it is showing on line 2 of Part V. With all of the employee contributions being Roth, a correct result would be $36,485 on that line as the deductible amount that transfers to Schedule 1 line 16. Also check to see that all of the amounts on Schedule 1 Part II make sense. That's were the effect of the solo 401(k) contributions you enter will be reflected.
