Question: The software is calculating the tax incorrectly despite the same figures , i have checked with different softwares and it seems that lodgeit is calculating incorrectly .


According to NoA person has special professional income.
This means user should fill this info in special professional income section in Other income. When this will be filled, the tax on taxable income will be correct.

Note: Not all amounts can be written to Special Professional Income. ATO instructions

If the income amount 41050 (or part of this) is presented in one of these fields (marked with yellow above) then it cannot be calculated for Special professional income. If it's not presented - then you should write it to field "Income not included elsewhere on this return", so then you will see the amount on Special professional income
