Retirement tax questions

Hi,

I have the exact same case except that my 2019 1099-R says

1. Gross Distribution as $11,500

2. Taxable amount as $11,500

3. Box 2(b) as X

 

Do I have to amend the 2018 return too and fill up the "wages & income" section with the distribution for 2018 as $5500(Although I didn't receive one since the transaction happened in 2019 Feb)?

 

Thanks,
