No charge to amend. But at I said above the missing 8606 forms can be file by themselves.
If the 2019 year end value of all Traditional IRA accounts was zero as indicated by what you reported on line 6 of the 8606 form then that dose not explain what happened to the $ 5,500 on line 2.
If you entered the $5,500 as past basis from the prior 8606 forms not filed and did not use that basis for past distributions then this could get very messy and you might need to take all of your past records to a tax professional who can put it all together. If you had previous years distributions/conversions then you might have paid too much tax.
You could just ignore the past basis and assume that it is zero and not file any past 8606, just amend 2019 to include the $6,000 on line 1 of the 8606 and enter zero for the past basis that puts zero on line 2. Then the taxable amount of the 2019 $6,002 conversion will be $2,00.
