For Year 2022-23, #/ITR/ITR1/ITR1_IncomeDeductions/OthersInc/OthersIncDtlsOthSrc/1/OthSrcOthAmount:

Same issue with me as well, did you find any solutions

In schedule OS, what is the income source which is negative?

IN INCOME WHEN THERE IS NEGATIVE SOURCE, DESELECT THAT ITEM AND THEN SUBMIT. IT WILL WORK

IN MY CASE THERE WAS INTREST FROM SAVING WHICH WAS SHOWING NEGATIVE AFTER DESELECTING THAT SOURCE SUBMISSION WAS SUCCESSFUL

This helps for the error "#/ITR/ITR1/ITR1_IncomeDeductions/OthersInc/OthersIncDtlsOthSrc/0/OthSrcNatureDesc: LTR is not a valid enum value];#;Please contact the developer of your utility with the error key"

Other income sources need to be corrected/unchecked/deleted where no data is there
