Retirement tax questions

Thanks.  That's the plan, except LESs aren't maintained electronically for that long and I don't commonly download them unless I need it for something.  My W2 for 2019 shows Oregon as my state of residence so hopefully, that is enough.  I opted to fill out their form online thinking it would be quicker but there was no option for uploading documents, so I either have to wait or give them a call.  At least this time I am able to deal with it before they put a lien against my bank account.  The state placed a lien against me while I was deployed in 2013.
