There is no problem - I will re-evaluate your situation if needed.
Following are included into your adjusted gross income:
--$28,800 disability social security income - 85% taxable $28800*85%=$24480
--$20,000 withdrawal from Traditional IRA - taxable
--$50,000 represents the basis of the company stock from the 401K Plan - taxable
--$12,000 Rental Income - assuming that is NET rental income (after deductions).
Total adjusted gross income - $106,480
Because you are disabled - there is no 10% penalty regardless of you age - sorry for confusion.
Assuming Married Filing Jointly, Standard deductions, no dependents, no other deductions or credits.
Assuming your spouse's income is also included above.
Your estimated tax liability would be ~$14,000.
Please feel free if you need any clarification or further adjustments
